Winnie Mandela, the political activist and former wife of Nelson Mandela who died last month at age 81, “became a target for her unwavering support of the ideas contained in the Freedom Charter,” said Marsha Coleman-Adebayo, host of the “What’s At Stake” program on radio station WPFW, in Washington. The socialist-oriented document became a rallying point for the left-wing of South Africa’s ruling African National Congress party. “There’s a pattern” in the ANC “throughout the decades of purging those elements out,” said Benjamin Woods, a co-founder of Students Against Mass Incarceration.
